Most efficiant use of dehumidifier


Say I want to dehumidify a certain area what is best thing to do, face the unit so it blows towards that area, or face it so it sucks the air from that area? My gut feeling tells me I should have it suck the air out of the area. If I make it push the conditioned air it's only going to push the humid air somewhere else instead of dehumidifying it. Am I correct?

Ideal is pulling the air in from the area that needs to be dehumidified
Exhaust is then sent outside in perfect setup

humid air moves toward non humid air.
so really it shouldn't matter where it is placed, it should work.

Where the warmer air is directed can make a difference
If the area continues to get warmer then more moisture will condense
My basement (unheated) is driest in the cold winter
I'd like to be able to vent the air outside, but hard to do with cement walls
And I don't want to cut into the rim joist

Overall if the heat is going into an enclosed space then it won't matter
But moving the air around via the exhaust can have an effect
If placed in a corner you won't get the best air movement & effect

In this case one area (crawl space) may be more damp
So you want to pull air from that area IMO
No expert...just based on my own basement & moving them around
